Yes, as charming as it is to be "remembered" by CMs, I have to believe that, with a few exceptions, a.) their memories are not that good; b.) we are not that memorable to begin with.
I would bet there is indeed some CRM in place, with extensive notes from prior cruises and our KTTW card photos to boot. I would further bet that if a server and/or stateroom attendant is matched up with you again (either by your request or by pure chance), they will get a heads-up and be tasked with brushing up on the details of your party so they appear to "remember" you. I would be dumbfounded if Disney were not doing something like this.
I would likewise not be surprised if there were longer-range RFID scanners at places like the bars or Vanellope's, so when you walk in, the scanner picks up your KTTW card, and the bartender or server is alerted to your info, like "Last time in Meridian, customer ordered a Gin Garden", or whatever.
